This binder is incredibly spacious and comes with a convenient strap for wearing it over the shoulder or across the body. It had a lot of extra pockets perfect for storing supplies and additional folders. It's been great for my daughter's class, it holds all her papers and keeps them well-organized.

Utility folder for school

My son keeps tearing his folder that he brings to school, so I went for a more sturdy option. This is perfect for storing all his papers and the best part is that it has a zipper on the side for easy access to things. No need to open the entire binder. Very well built and good quality.

Good Product. Worth the money.

Bought this for my 6th grader. Was a perfect size to carry all her folders and large enough to fit her Chromebook. She loves the shoulder strap that comes with it so she can carry it hands free!

Decent size and space.

Decent size and space. Good project to keep documents safe and handy to take anywhere.

Great Binder

This binder is solid and can hold a lot. We returned it for personal preference reasons; however, as a parent, I thought this was a solid case. I took a star away for structure. I thought it could be more durable with a stronger internal structure, but you would also lose the flexibility of it. The material seems strong.
